Hi Susan,

I think the issue you had was the caching because of the SG Optimizer plugin.

So disabled 2 plugins and was able to upload the images for the testimonials.

I did it for all 3.

When developing a site you must disable all caching because when you make a change on the site you won’t see if reflected on the front-end until you clear the cache.

If you need further help, let me know.
